My professor tricked me!
Yesterday I took my final exam for economics, I needed a 90 to get an A in this class. This is what happened, there was a question about the value of a public good and I knew the answer. Anyway, I wanted to make sure that the question was not stated incorrectly, because I could only miss 5 questions in order to maintain my 90. So, I asked my professor about the question for clarity, "is it 150 people who individually value the park at 2, or is it their total value", she told me individually with a suspicious smile. I ended up changing my answer to what she stated, but after I turned in my exam I realized that she told me the wrong thing. I'M MAD AT HER! because I think I might have missed more than 5 now.
